Not multistories. And even when they build grand structures on hills/mountains of Himalayan ranges in ancient time - nature spared none when earthquake stuck or flash floods. But right now whats happening in hills is literally pillage of the mountains. I have seen a beautiful serene place turned into concrete unplanned mess within lifetime in hills. And one look at the style of 'new' constructions can tell God forbade a cloud burst or earthquake can turn all those new constructions shall wash away or fall down like pack of cards.people have lived in hill slopes and valleys for centuries you retard
